Run lisp in emacs
You can run a builtin or loaded lisp module command in Emacs like this (example - starting the speedbar):
M-x speedbar
You can also try things out in the *scratch* buffer. For example:
- Bring to front the *scratch* buffer
- Type your lisp. e.g. (+ 2 3)
- Press Ctrl+X Crtl+E
- Watch the result in the bottom (echo) part of the Emacs window/screen
How to open new files in already open Emacs window (using gnuserv)
http://www.debian-administration.org/articles/257
Shortcut:
apt-get install gnuserv
Add to your .emacs configuration file the following:
;; ;; Start GNUServe process when starting up. This lets us send new files ;; to previously spawned emacs process. ;; (load "gnuserv-compat") (load-library "gnuserv") (gnuserv-start) ;; When loading files reuse existing frames. (setq gnuserv-frame (car (frame-list))) ;; Stop annoying prompt on kill buffer but member of gnuserv (setq kill-buffer-query-functions nil)
Create a shortcut script to call emacs and alias emacs command with this:
#!/bin/sh
# ~/bin/emacs
# "apt-get install lsof" - if you're missing "lsof".
lsof /usr/bin/emacs-snapshot | grep $USER >/dev/null 2>&1
if [ "$?" -eq "1" ]; then
/usr/bin/emacs-snapshot $* &
else
/usr/bin/gnuclient $* &
fi
Pretty fonts for Emacs editor
How to replace built-in emacs fonts. http://peadrop.com/blog/2007/01/06/pretty-emacs/
Shorcut:
sudo aptitude update sudo aptitude install emacs-snapshot emacs-snapshot-el echo "Emacs.font: Monospace-10" >> ~/.Xresources xrdb -merge ~/.Xresources
Note, if you get the "No fonts match `Monospace-10'" message, make sure you are running the emacs-snapshot and not your previous emacs version.
Emacs and UTF-8
Setting up Emacs to prefer UTF-8 encoding for files: add to .emacs file:
(setq locale-coding-system 'utf-8) (set-terminal-coding-system 'utf-8) (set-keyboard-coding-system 'utf-8) (set-selection-coding-system 'utf-8) (prefer-coding-system 'utf-8)
The command to tell emacs that the file in the buffer is utf-8 instead of latin-1
M-x set-buffer-file-coding-system (Usually bound to C-x RET f)
How to insert some text in the file (in comments) to tell emacs which encoding to use.
Insert the coding File Variable:
Put the following on one of the first two lines:
-*- coding:utf-8; -*-
or put:
Local Variables: coding: utf-8 End:
in the last 512 bytes of the file.
